【正文】 s the subject of bined milling machine spindle ponents. First of all, for the processing of parts to start with a general program of machine design, machine tool and then determine the overall layout, then the design of the main ponents. Components in the design of the spindle to spindle for clues, to meet the stiffness and precision required to plete the other (such as bearings, axial adjustment agencies, locking, etc.) the design of all parts. Design mechanical processing order to follow the following principles 1) To ensure that all parts drawings on the realization of the technical requirements. 2) Program must be able to meet production requirements. 3) To meet the technical requirements and requirements of the production program, under the premise of the minimum requirements of cost, low energy. 4) Minimize the labor intensity of workers, protection of production safety. This product is based on user requirements and design, the user discussion after passing the production, hope the guide, identified.
